What Is Backflow—and Why Georgia Homeowners Should Test Annually

A few years ago, a homeowner in Brooks called us in a panic.


They had noticed a strange smell in the water coming from their outside hose spigot. The water wasn’t clear, either—and it had a slight, chemical-like odor.


They weren’t imagining things. Their irrigation system had developed a backflow issue, and untreated water from the sprinkler line had started reversing into the home’s drinking supply. Thankfully, they caught it early—but many people don’t.


Backflow is one of those silent problems you don’t notice… until it affects your health. That’s why today, we’re answering the question:


What is a backflow preventer, and why does it matter for homeowners in Georgia?


What Is Backflow?


Put simply, backflow is the unwanted reversal of water flow in your plumbing system.

Instead of water flowing from the municipal line into your home, a sudden pressure change can cause it to flow backward, potentially pulling contaminated water from outside systems—like irrigation, pools, fire sprinklers, or even hose attachments—into your drinking water supply.


What Is a Backflow Preventer?


A backflow preventer is a special plumbing device installed on your water line to stop dirty or hazardous water from reversing into your clean supply.


It acts like a one-way valve: water can only move in the correct direction. These are often required on:


  • Irrigation systems

  • Commercial kitchens

  • Medical buildings

  • Apartment complexes

  • Fire suppression systems

  • Homes with outdoor hose bibs or well water

In fact, most Georgia municipalities require annual backflow inspection and certification—especially if your home or business has a cross-connection risk.


Why Does Backflow Happen?


Backflow usually occurs when there’s a drop in water pressure from the city’s supply line. This can be caused by:


  • A water main break

  • Nearby firefighting activity

  • Frozen pipes

  • Backpressure from pumps or elevated storage tanks

When pressure drops, water from your home or outdoor systems can be pulled into the city’s clean water supply, carrying pesticides, bacteria, or chemicals right along with it.

That’s not just gross—it’s a serious public health risk.


Do I Need Backflow Testing in Georgia?


In most cases, yes.


Here in Georgia, many water authorities—including those in Fayette, Coweta, Spalding, and Pike Countiesrequire annual backflow testing for properties with irrigation systems or other potential cross-connections.


Even if it’s not legally required at your address, testing your backflow preventer once a year is one of the easiest ways to protect your home and family from unseen water contamination.


What Happens During Backflow Testing?


At Buffington’s Plumbing, our certified backflow testing process includes:


  1. Checking your preventer valve for proper operation

  2. Measuring pressure levels to confirm no reverse flow is happening

  3. Identifying leaks, seal failures, or malfunctioning parts

  4. Completing required paperwork and reporting to the city (if applicable)

Testing usually takes less than an hour—and if your system needs repairs or replacement, we’ll explain your options clearly and get it fixed fast.

Garbage disposals make cleaning up after meals quick and convenient, but they're not designed to handle everything. Putting the wrong items down your disposal can lead to stubborn clogs, damaged blades, unpleasant odors, and even expensive plumbing repairs. Whether you're cleaning up after a backyard barbecue or preparing fresh summer meals, knowing what not to put down your garbage disposal can help keep your kitchen plumbing working properly. If you're upgrading your kitchen or adding an outdoor cooking area, Buffington's Plumbing also offers Gas Line Installation & Repair for gas ranges, outdoor kitchens, and built-in grills. At Buffington's Plumbing, we've helped homeowners throughout Brooks, Griffin, Fayetteville, Peachtree City, Newnan, Zebulon, and surrounding South Metro Atlanta communities resolve clogged drains, jammed garbage disposals, and other common kitchen plumbing issues. Why Garbage Disposals Get Clogged 1. Grease, Oil, and Cooking Fat One of the biggest mistakes homeowners make is pouring grease or cooking oil down the drain. While liquids may seem harmless, grease hardens as it cools and sticks to the inside of your pipes. Over time, this buildup can: Restrict water flow Trap food particles Cause stubborn drain clogs Lead to unpleasant odors Instead, allow grease to cool, then dispose of it in a sealed container in the trash. 2. Coffee Grounds Coffee grounds don't dissolve in water. Instead, they collect inside your plumbing system and combine with grease or soap residue to create thick blockages. Dispose of coffee grounds in the trash or add them to your compost pile instead. 3. Eggshells Many people believe eggshells sharpen disposal blades, but that's a common myth. The thin membrane inside the shell can wrap around moving parts while crushed shell pieces may collect inside pipes and contribute to clogs. 4. Fibrous Fruits and Vegetables Certain produce contains long fibers that can wrap around your disposal's motor. Avoid putting items like: Celery Corn husks Asparagus Artichokes Onion skins Banana peels These foods are better suited for the trash or compost bin. 5. Pasta, Rice, and Bread Pasta, rice, and bread continue absorbing water after they're discarded. As they expand, they create a thick, sticky mass that can clog both your disposal and drain lines. It's best to scrape these leftovers into the trash before washing dishes. 6. Bones and Fruit Pits Even powerful garbage disposals aren't designed to grind hard materials like: Chicken bones Beef bones Peach pits Avocado pits Corn cobs These items can damage internal components or jam the disposal completely. 7. Potato Peels Large amounts of potato peels create a starchy paste that sticks inside pipes and slows drainage. While a few small pieces may not cause problems, it's best to throw most potato peels in the trash. 8. Seafood Shells Shrimp shells, crab shells, lobster shells, and oyster shells are too hard for most garbage disposals. These materials can dull grinding components and create stubborn blockages. 9. Non-Food Items It may sound obvious, but accidental items often end up in the disposal. Keep these out: Plastic wrappers Twist ties Paper towels Sponges Fruit stickers Glass Metal utensils These objects can quickly damage the disposal and require professional repairs. How to Keep Your Garbage Disposal Working Properly A few simple habits can extend the life of your garbage disposal: Always run cold water before, during, and after using the disposal. Feed food waste gradually instead of all at once. Cut larger food scraps into smaller pieces. Clean the disposal regularly with ice cubes and citrus peels for a fresher smell. Never overload the disposal. Regular care helps prevent clogs while keeping your kitchen plumbing flowing smoothly.
